Are you really considering Fluorescent lighting for a new install? LED is the way to go.Building 30x40x12 metal building poor eyesight best lighting for bldg t5 or t8
T5 and T8 are the configuration, not the light output. I can't imagine enough light in any garage situation that would cause problems with glare unless you work with reflective surfaces. I look for tubes around 5,000 lumens and 5000C colour temp to get what works for me. You can always add, subtract or move lights around, but IMHO you need enough sources that you don't have shadow issues rather than worrying about glare.Building 30x40x12 metal bldg have poor eyesight so which would be better t5 or t8 led?

t5 and t8 refers to size of the tube in fluorescent lighting. I certainly hope you are not considering fluorescent lights for a new build. LED is the way to go.
BTW, it seems to be that you started 2 separate threads in 2 different GJ topics asking the same question. Perhaps you should ask a moderator to combine them or eliminate one of them.

glare really only happens when direct light hits a shiny reflective surface , doesn't it? and that will happen with virtually any direct lighting .
as mentioned, t5 & t8 are only the pin configurations, nothing to do with light specifications.
I think T8 is easier to find in LED fro retrofit bulbs. as far as colour temp, I like the brighter white for work areas, and softer light for non work/ home type situations

Glare in my lighting design work is generally fixtures and their cut off, seeing the bulb across the room. Low glare fixtures are by definition 45 degree cut off.
Thanks to all who answered my question even tho I did put it in 2 places. Lighting a 30x40 metal bldg is a lot more complicated then just screwing in a couple of light bulbs. I am going to use LED.

T= tubular, 5 and 8 refer to the diameters in eight of a inch.t5 & t8 are only the pin configurations, nothing to do with light specifications.
T5 (5/8" dia), and T8 (1" dia).
That true of all bulbs. (First the shape of the bulb, then the diameter)
R40 = reflector bulb with 5" diameter, PAR38= parabolic reflector with 4.75" diameter etc.

Prime lights will give you a lighting layout if you give them your building dimensions. My building is 20 x 26 x 10 and I have 8, 4 foot Prime light led fixtures in it and it’s about as bright as an operating room.

I am sure this isn’t the “best” option, but it worked really well for me and when I did it, it was about the cheapest I could put up led lights. There may be less expensive/better options now.
I bought el cheapo 4 ft t8 fixtures from Home Depot. Bought tombstones for the ends off Amazon. Only one side of the fixture is wired. I used these bulbs so I had interchangeable led’s. I have about 2200 sq ft, of shop and 10 ft ceilings. I used between 34-35 fixtures I think. Lighting is great in my shop. I haven’t lost any bulbs so far 3 years in.

I am a fan of using fluorescent fixtures stripped of the ballast(s) & using ballast bypass LED's, that way you don't have to toss the whole fixture when it fails, & it's long past the time to charge a $100-150.00 recycling fee each for fixtures with built in LED's/ drivers, there would be screaming ****** murder but it's wasteful, all to keep ChiCom labor camps & organ harvesting centers busy+ schlepping them all that distance.

And just for contrast, I'd recommend LED fixtures, not replacement tubes. Lower cost initially, longer life - double by some reports, more lumens per watt or fewer watts for same amount of light, and the possibility of dimming or better dimming. I also like the design options but that's just a preference.
